The problem

I received this error following the steps written in home assistant readme (Trouble shooting: A captcha is required):

{"error":"Failed to register: [422] Bad response: 422 : {"errors":["number value is not a valid E164 number"]} (NonSuccessfulResponseCodeException)\n"}

the phone number is in E164 format: +39339xxxxxxx,
do you have some suggestions?

Please post the actual curl command (with the redacted phone number!) you are using. Is it a landline number?

curl -X POST -H "Content-Type: application/json" -d '{"captcha":"signalcaptcha://signal-hcaptcha.5fad97ac-7dXXXXXXXX", "use_voice": false}' 'http://192.168.1.101:8080/v1/register/+39339XXXYYYY>'

-X POST -H "Content-Type: application/json" -d '{"captcha":"signalcaptcha://signal-hcaptcha.5fad97ac-7dXXXXXXXX", "use_voice": false}' 'http://192.168.1.101:8080/v1/register/+39339XXXYYYY>'

I guess the > in +39339XXXYYYY> is just a typo and comes from the redaction?

Is it a landline number?
